My invention relates to an improved bumper for vehicles and more particularly.

to a bumper adaptable for use on such" vehicles as VillBel6Cl.[lI1\ELllClCllZLlIS. a

An object of my invention is to. provide an improved bumper, whichmay be easily and quickly attached or detached to or from a vehicle such as a wheeled invalid chair.

Another object of my invention is to-provide a bumper which will not only protect the vehicle carrying it, but will also protect I against injury articles against, whichfthe vention itself-will be apparent by reference I to the following descriptionof an embodiment of my invention, and in which description reference will be had to the accompanying drawings, forming a partof this specification.

Referring to the drawings:

Fig.1 shows a front elevational view of,

an invalid chair with an embodiment of my invention applied thereto; I

Fig. 2 shows aside elevational view of the embodiment of my invention'as shown in Fig. 1; a

Fig. 3 shows a top plan view of the embodiment of the foregoing figures, certain upper ends at 42 and 4.3, each to a one vehicular parts being omitted in this view; Fig, 4: shows a rear elevational view thereof; and i c Fig. 5 shows a perspective view of a fragment of the rubber strip, core and fastening .means enlarged. I i

all the figures of the draw- Referring to ings, in all of which like parts are designated by like reference characters, 1 generally designates an invalid chair provided with a back 3, adapted to-be inclined rear wardly from the position in Figs. 1 and 2 to various positions approachmg ai'horlzon tal position by virtue of thepairs of hinges 36, 62, and 48. A sector 38 and ratchet 'detent 39, releasably engageable therewith,

are adapted to hold the back in any desired inclined position. At 2, I show a chair'seat, spring mountedon the chair frame 28, a plurality of helical springs 14, secured at their upper ends to the seat and at their lower ends toa skeletonplatform comprising a pair of strips 15,

whichare each supported at their front and rear ends by a pair of angle iron posts 1 7 The posts 17 are mounted rigidly uponthe chassis frame side bars 16, andreenforcing truss bars 24. extenddiagonally betweenthe ends of the strips 15 and the chassis side;

bars 16, to which they are rigidly secured,

the various parts comprising thechassis frame and spring carrying platform assembled by means of securing rivets or by welding, or in any other well known way.

At 7 and 8,. I- provide a pair of leg rests comprisingfoot boards 9 and 10, respectively, hinged'to the longitudinally extending portions 7 and. 8- tao Th hinging bracket 49' interconnectin the foot rests 9 and 1 0 and the leg rests and 8, comprise ratchet retaining means for holding thefoot rests 9 and '10 in any desired angular position, relative to'that of the leg rests 7 and 8,

from a position wherein the foot rests extend at right angles thereto, to a position wherein the foot rests extend longitudinally from the leg rests. This mechanism, although it may;

take variousforms, may comprise a. ratchet. sector carried by the one hinged partand a spring pressed ratchet pawl engageable there- 1 with and adapted to enter any'desired one of the notches in the sector; This mechanism;

being no part of the present invention, is not specifically illustrated.

The leg rests 7 and 8 are hinged at'theirof a pair of leg rest supporting boardsfiandj 11, which aretelescopable under the seat 2,.

being retained in telescoping position therewith by a pair of metallic strips 88 and 89 which are bolted to the underside ofthe seat and extend transversely thereof, the first.

under the extreme forward portion of the seat andthesecond being spacedgupwardly therefrom, eachcontaining downwardly ex-. tending loops 44 and A5 adapted to act as trackways for the sliding telescopable boards 6 and 11. This arrangement permits the extension of the leg rests .7and 8 to any desired position forwardly of the seat 2 and, togetherwith the hinging of theleg tests at.

the point 43 with the boards when the leg rests and foot boards are in extended position, forms with the boards, the seat 2 and back 3, a reclining couch.

Pivoted at 4, to the sides of the seat and adjacent the forward'ends thereof, are a pairof vertical disposed posts, 32 and 33, which are adapted to support the forward ends of the arm rests 34 and 35. Thearm rests 34 and 85 are supported by longitudis nally extending metallic bars 61 having rear depending portions which are perforated to admit a hinge pin 40, which swivelably connects the back to the arms. To a depending portion 68 "of the member 61', each sector 38 is pivotally secured, each of the sectors havill) ing notches on its under side adapted to engage with a detent 39 carried on a metallic strip 64, secured'to the side of the chair back. The strips 64 and bars 61 are-pix" oted together at'86 to permit various angu-' lar adjustments ofthe back by adjustment of the sector 38 and detent'39Q The leg rests and foot rests may be adjusted vertically 'by virtue of the tooth sector 65 pivoted to the leg rests at 66 and supported at the rear by cords 67 and 68 which are supported on the arm rests at 69 and 7 O. The teeth of the sectors are adapted to engage depending ratchets 71 and 7 2 supported by the horizontal bars 6 and 11 and adapted to slide horizontally when the leg restsare horizontally adjusted and adapted to retain theteeth of the sector tosupport the leg rests in any of their vertical adjusted positions;

Depending from the forward end of the frame 16 are a pair of anti-tiltingdevices and 100.

The frame and chair heretofore described. are supported by a pair of large wheels 50- and 51 carried on the axle 26 supported in the forward end of the frame in suitable journals or bearings.

To the vehicle as above described, I apply a bumper comprising a metallic support 20,

preferably made ofchanncl iron, and a facing 21 of rubber, the rubber facing having a rectangular bore 7 41 and the iron support presenting a groove 19.on-its outer surface.

with the metallic strip core in place thereinis sh0wn,I show, subsequent to the insertion of the strip within the rubber, a metal'licpin 93 through an opening 94 in the steel strip,

the pin being insertable through a hole 95' extending from the rounded outer face 92 of the rubber to the opening 94 in the steel strip,the pin being insertable through a hole '95 extending from the rounded outer face 92 of the rubber to the opening 94- in the strip and aligned therewith, there being a plurality of holes 95 through the rubber and openings 94 in the steel strlp provided at in tervals throughout the composlte facing element; Prior to insertion of the composite facing to the channeliron 20, I insert pins,

such as the pin 98, through the different aligned openings ,95-94 anrtproject them through the inward extension 18 off-the rubber.

The composite facing, having the rubber exterior and the steel strip interior, is then i applied with its projection 18 pressed into the groove 19 of the channed iron,'and the pins 93 will have their ends projected through openings provided for the purpose;

extending through the channel i'ron;20 QThe securing of the composite facing, havlng a rubber exterior, to the-channel iron then effected by riveting overthe endsgof the metallic pins 93 which project through the channel iron. Up to this point in the operation of formlng my improved bumper element, the channel iron and, facing are pre-' 'sumed' to be substantially stralght, but after the riveting of the facing to the channel iron the same-will be bent into 'thesh'ape illu"- trated best' inFig. 3, wherein a bend 13 is given to the bumper at one 'endadjacent the rear of the large wheels 50 and 51-, and I another bend is imparted to it at the point 84adjacentthe front ends of the wheels. v p v At 96, the composite bumper, comprising channel iron and rubber facing with metallic core, is given a reverse rec-entrant bend to form a hook end 23, and which hook end is adapted to embrace the caster head 22, each of the two such heads being rigidly carried 1 at a forward corner of the chassis frame. The chassis frame comprises, as has been noted, the frame side bar element 16 and front axle-26, and comprises a transverse bar 98 rigidlyjoining together the forward ends of the frame side bar elements 16. -At 25, I show a loop projecting from the inner face of the channel iron 20, to which it is riveted or otherwise secured at 85 and which loop has an upwardly extending portion perforated at 12 to admit the ends of the rear 7 axle 26 which projects through the perforations.

support the bumper on the axle ends but retaining the wheels 50 and 51 on theaxlcs together with the hand rails 30 and 31-, which are secured to the wheels and rotate with v p we.

filed May 12, 1926, only a general description thereof being herein given to facilitate a ready understanding of the present inven tion.

The bumper extends forwardly'along the side of the chair and substantially horizontal with the supporting surface for the chair,

to a point adjacent the forward end of the wheel treads 27 of the large forward wheels of the chair. The forward end of the bumper is curved inwardly at 13, and is also bent inwardly at 84 so that the hand grips and wheels are partly surrounded by the bumper. The bracket is bent at 97 so as to space the bumper from the wheeltreads and the hand grips.

A bumper applied to an invalid chair in project laterally of all parts of the chair and the objects and absorb any prevent contact of any, metallic or hard parts thereof with other objects. The rubber facing of the bumper will strike against therefrom.

It will be noted that the caster wheels 53 and 54, upon rearward movements of the vehicle, will swivel about its head 22, and that th portion 73 of the wheel will then take an advance position relative to the direction of movement of the vehicle but that at such advanced position it will be disposed rearwardly in the lineof motion with respect to the entire curved end 96 of the bumper. In this Way, it will but infrequently happen that the caster wheel 53 will com into contact with extraneous objects,'and all of the wheels preferably having rubber tires and the bumper being faced with rubber, at all times the vehicle is prevented from the liklihood of'having any but rubber faced portions coming in contact with extraneous objects.

Having thus described my invention in a single embodiment, I am aware that numerous and extensive departures may be made shock resulting from the embodiment herein illustrated and from: the

described but without departing spirit and scope of the'invention. I 'clain1:1 Y I -1'; In an invalidfchair, the'combinati'on L With a pair of large propelling wheels, one
